Overview
The MAX11049ECB+T is an 8-channel, 16-bit, simultaneous sampling Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is packaged in a 64-pin TQFP and features independent track and hold (T/H) and Successive Approximation Register (SAR) circuitry, enabling simultaneous sampling at 250 kSPS for each channel. It accepts input voltages ranging from 0 to +5V and includes overrange protection with internal ±20mA input clamps. The ADC operates with a 4.75V to 5.25V analog supply and a separate flexible 2.7V to 5.25V digital supply, allowing for interfacing with the host without a level shifter.
